Specification of Letters Patent.

Patented May 12, 1908.

Application filed February 12, 1906. Serial No. 300,596.

lowing is a full, clear, and exact description,

reference being had to the accompanying drawings, forming part of this specification. in which-- 1 Figures 1 and mw the rolls with the sucwessive passes zl-Z'z'tflgill in accord:.mce with my invention in two three-high mills, and Fig. 3 is a view similar to Fig. 2 showing a iilerent arrangementof the finishing passes. My invention. relates to apparatus for rolling shapes having wide flanges, and it is designed to produce such shapes without the use of universal mills.

In the drawing, Fig. 1 shows a three-high mill having rolls and i, and containing five passes. I start with a bloom or billet, which in passing through the first pass (1 is provided with the longer diagonally opposite fiangos 5 and 6 and with the shorter rudimentary flanges 7 and 8. The metal then returns tl' rough the pass 5, in which the flanges 7 and 8 are widened and the fianges 5 and 6 are contained in the dead groove, and hence not widened. It will be noted that the flan es 5 and 6 which are in the live groove in the first pass are in the dead grooves in the second pass. It will also be seen that the live grooves are formed by substantially fiat faces which. taper or converge toward each other outwardly with an open space at the end of the T he live grooves therefore fare always o en,and the dead grooves always closed; and y making the faces of the live grooves substantially fiat and outwardly con- 40 verging, I obtain the very substantial widening of two of the flanges.

In the third pass 0 the fianges'5 and 6 are Within the live grooves and are therefore -widened while the flanges 7 and 8 are within the dead grooves and are not widened. In the next-pass d the flanges 2 and 8 are widened in the live open grooves, while the flanges 5 and 6 are within the closed dead grooves. I.

In the fifth pass a the flanges 5 and 6 are widened in the open live grooves, while the flanges 7 and 8 are within t e dead grooves.

-In the ass f of the second set of rolls 9, 10 and 11, the flanges 7 and 8 are widened and 35 made thinner in the live grooves, While the flanges 5' and are within the dead grooves.

In this the sixth pass, the flanged shape, which in this case is a wide flanged I-beam, is brought subs .antially to its final dimensions, but the flanges are inclined outwardly in opposite directions. The next pass or passes are merely bonding passes which bend the flanges into parallel planes to form the Ibeam.

In the seventh pass g the'web 12 is substantially horizontal, and the upper flanges 6 and 7 are bent into proper position, while the lower flanges 5 and 8 remain bent outwardly.

In the final eighth pass 7L, the flange 12 is horizontal, and the lower flanges 5 and 8 are vent into planes at right angles to the Web, thereby finishing the beam. In this second set of rolls I have shown supplemental passes g and it, so that the metal may be passed through either 9 or g in. the seventh pass and either it or 71 in the ei hth pass.

It will be noted that in the bending pass or passes the web is supported by therolls at the same time that the flanges are being bent to form. This is an important feature of my invention, since it prevents buckling of the web and insures a ood product. It will also be noted that in alIof the reducing passes the web is at an angle to the axes of the rolls, this angle being reversed in successive passes.

1 In the modified passes of Fig. 3 the sixth pass f" is the same as the pass fof Fig. 2, but 111 the first bending pass 9* the web 12 is not horizontal, but is inclined, and none of the flanges are bent into final position in this pass. All of the flanges are bent toward their final position, and then in the final pass W the web 12 is horizontal and the flanges 5 6,' 7 and 8 are bent to final position. In this case, as in the first form, the web is sup- )orted by the rolls at-the same time that the ilanges are being bent into their final )osi tion. There is also no turning of the b ank to a position at right angles to the previous pass. It will be noted that this is the case with all the passes.

The advantages of my invention result from the obtaining of shapes having wide flanges by means of ordinary mills other than universal mills having horizontal and vertical rolls.

By arranging the diagonally opposite.

flanges where such, are present, alternately in the dead and live grooves, and by shaping the live grooves in the manner above described, I can obtain much wider and thinner flanges than have heretofore been gotten by I this apparatus'is avoided.

. the use of ordinary mills. The bending of the flanged shape in passes which support the web is also of importance, as this prevents distortion of the web and insures a' good product. It also avoids the necessity for turning the blank to an angle at 90 to the previous ass a 7 It not Being necessary to turn the blank during therolling operation, the usual manipulators or other turning devices usually ernloyed are rendered unnecessary, and the flifliculties experienced in the operation of Instead of passing any flange alternately through a live groove and then through a dead groove at each successive pass, the flange may be passed through two live grooves before entering a dead groove, or two dead grooves before entering a live groove. This mightbe done where the mill would not permit a heavy draft, or for other reasons, and I intend to cover such variation in my claims.

Variations may be made in the mill or mills emplo ed, in the contour of the flanged I shape eing rolled, in the number and'width of the flanges, 850., without departing from my invention. 7
